Optimal target search on a fast folding polymer chain with volume exchange

arXiv:cond-mat/0510072 · doi:10.1103/PhysRevLett.95.260603

Abstract

We study the search process of a target on a rapidly folding polymer (`DNA') by an ensemble of particles (`proteins'), whose search combines 1D diffusion along the chain, Levy type diffusion mediated by chain looping, and volume exchange. A rich behavior of the search process is obtained with respect to the physical parameters, in particular, for the optimal search.
